Machine resumes straight after suspend to RAM (or disk)

Hi,

I thought I'd enable suspend and resume on my desktop machine so I
could save myself some time in the morning when I restart the machine.
The machine is fairly standard Intel Core Duo based system (lspci
attached). However when I execute pm-suspend (or Gentoo's own
hibernate-script) the system does suspend but resumes immediately. To
add insult to injury the ethernet doesn't come back properly and needs
a reboot to reset it.

I've played about a little with the ACPI debug stuff but it's easy to
overflow the dmesg buffer. The relevant section around the
suspend/resume looks like:

Unfortunately the ACPI stuff is all Greek to me. If anyone wants
additional debug information then please let me know.

So any ideas?
